I am a member of the district of recreation and will be helping to construct the best posible ark we could have to deliver the goods we need to build parks and recreation centers,
As you know soon we will have to leave our home and journey to the great Aurora 56z, here is some information about the Ark I have constructed,

Desalination:
Methods
The traditional process used in these operations is vacuums desalination—essentially the boiling of water at less than atmospheric pressure and thus a much lower temperature than normal. This is because the boiling of a liquid occurs when the vapour pressure equals the ambient pressure and vapor pressure increases with temperature. Thus, because of the reduced temperature, energy is saved. Multistage flash distillation, a leading method, accounted for 85% of production worldwide in 2004.
The principal competing processes use membranes to desalinate, principally applying reverse osmosis technology. Membrane processes use semipermeable membranes and pressure to separate salts from water. Reverse osmosis plant membrane systems typically use less energy than thermal distillation, which has led to a reduction in overall desalination costs over the past decade. Desalination remains energy intensive, however, and future costs will continue to depend on the price of both energy and desalination technology.
A desalination plant essentially separates saline water into two streams: one with a low concentration of dissolved salts (the fresh water stream) and the other containing the remaining dissolved salts (the concentrate or brine stream). The plant requires energy to operate and can use a number of different technologies for the separation of the saline water. The amount of the feed water discharged to waste in the brine stream varies from 20 to 70 percent of the feed flow, depending on the technology employed and the salt content of the feed water. Desalination is becoming more economically viable as the technology improves. Desalination plants can be provided in a wide range of outputs to cater for small isolated communities or to contribute substantially to water supplies for large cities and even for irrigation (Spain, United Arab Emirates). One of the processes for desalination is reverse osmosis (RO). It is a membrane separation process in which the water from a pressurized saline solution is separated from the dissolved material by flowing through a membrane. No heating is necessary for this separation. The major energy required for desalination is for pressurizing the feed water, typically up to 62 atmospheres for seawater. In principle, the saline feed water is pumped into a closed vessel where it is pressurized to overcome the osmotic pressure of the solution before diffusing through the membrane. As a portion of the water passes through the membrane, the remaining feed water increases in salt content. This portion of this feed water is then discharged without passing through the membrane.
Desalination of seawater or brackish groundwater or river water for a public potable water supply is increasingly being considered or adopted around the world in areas where demand has been increasing beyond sustainable supply, where water sources are fragile or overdrawn and climate change is making previously reliable sources unreliable. Rapidly increasing populations are also placing pressure on existing water sources, forcing governments to turn to inter alia desalination to provide additional water supplies when existing sources are fully extended. There is also potential for desalination to process already treated wastewater, normally returned to the environment, to a higher quality level for use in industry or mining processing, thus taking industrial demand away from public water supplies. An additional benefit of this would be reducing the volume of treated wastewater disposed to the environment. This option can produce water at a lower cost of treating sea water in many cases. Desalination for major public supply is already employed fairly extensively in areas such as the Middle East and North Africa, the Caribbean, Southern Europe and now in China, Singapore and the USA.
Minecraft,
So far on minecraft Luca D on I have made a roller coaster and a desalination plant, the desalination plant is 20 cubic meters high and 15 cubic meters wide (20 blocks by 15 blocks), the roller coaster is called the flames of furry and goes for 30 seconds. Next session I'm going to build a jungle ropes course and hopefully finish it.
